to perform oral sex while upright like when standing. Originates in the US navy, when a lower bunkmate would perform oral sex on the upper bunkmate while the upper bunkmate would sit or lie on the upper bunk. This is an infrequently used definition of the term and, when used, is often reserved for oral sex performed on a male.

Former US Representative Eric Massa has been accused of undoing the pants of and attempting to snorkle his sleeping bunkmate while proudly serving in the US Navy.
